Flights from Newark to Seattle: the best tips from KAYAK users' own experiences

Insights shared by verified travellers who flew the route from Newark to Seattle 
Juan LuisFlew with United AirlinesEWR-SEAApr 2025
New terminal in NSR is the better and more beautiful I ever seen.
Verified travelerFlew with Alaska AirlinesEWR-SEASep 2024
Buy something in the airport to eat before boarding as its a long flight and the snacks are not enough unless you plan to sleep the whole ride.
KatieFlew with Alaska AirlinesEWR-SEAJun 2024
Alaska Airlines offered free checked bag and personal bag with ticket price which I found to be very reasonable. Of the other airlines I found Alaska Airlines to be most comfortable, have friendly and efficient staff and reasonable pricing. Newark airport is rather easy to navigate given its size. We found Seattle airport to be a bit difficult to navigate, especially when returning a rental. Customers in this instance should allow extra time for the car return, bus to the terminal and navigating through the airport which included several monorails to get to our boarding terminal and through security to the gate. Signage for security was confusing we needed to ask for direction and restaurants were limited and short staffed once through security. As long as you allow for extra time, we found it to be relatively painless.
kFlew with Alaska AirlinesEWR-SEAJan 2024
Although there was a slight delay in departure and arrival, I was impressed with the safety-conscious approach.

Booked a premium seats weeks ago and got an email the night before that id instead be seated in the cabin. Only reason I booked this overnight flight was for the better seating. All they are doing to compensate is giving a $29 coupon to use on another flight. I won’t be booking this airline again.

Booked a premium seats weeks ago and got an email the night before that id instead be seated in the cabin. Only reason I booked this overnight flight was for the better seating. All they are doing to compensate is giving a $29 coupon to use on another flight. I won’t be booking this airline again.

It was all great all around. Will travel with Alaska next trip.

There was no seating at the gate, no where to charge your devices, super crowded. Boarding in group F meant all luggage space was taken when it was time for me to board. The boarding crew was short with everyone and seemed irritated. The luggage space was insufficient, the seat was too small for me (6'4") and very uncomfortable trip. I was in a middle seat between a person snoring the whole trip and a person with very strong body odor. The flight crew was terse and unfriendly, seemed irritated and impatient. Yelled a lot at people with earbuds in, understandable. Finally, we arrived 10 minutes early, only to sit on the tarmac for 20 minutes and wait for a gate. Worst flight experience I've had in years.

Flight 351 SEA to BOI was terrible. We got to cruising altitude and I needed to use the restroom but the fasten seatbelt sign never came off. There was no turbulence and I'd felt the plane level off so I stood up to use the restroom about 15 minutes after we leveled off. The stewardess went over the intercom and said I needed to be seated because the captain hadn't turned off the fasten seatbelt sign....Which... Fair.... But not five minutes later she went and used the bathroom. Felt very unprofessional to leave a paying customer with a burning urethra for the entire flight and bark at them to sit down and still use the bathroom yourself. They never did turn off the seatbelt sign.

For longer trips, snacks are puny, boring and don’t have ANY nutritional value.

Upgraded to first class both times .The flight attendant Spicy Tim.was excellent and very amusing.

Close boarding too early we’re willing to not let people on flight that could not check in. What ever happened to customer service? Three of us had to fight to get on plane shameful

Made us check our carry on,even though there was plenty of room because they didn't check with the flight crew. Also boarding was 40min late, due to the plane being on the wrong side of the airport. Also their app didn't record my tsa precheck

The flight was delayed due to a safety check. Why couldn't that have been done ahead of time? We got to Seattle with enough time to make our connecting flight but they kept changing the gate so we missed it. There were at least ten of us who missed the flight. The airline was aware. They could have waited. They didn't. Our new flight was not for seven hours and then was delayed another two hours. We got the last seats which don't recline. Super uncomfortable after a long day spent at the worst airport. Did they offer us a meal voucher or anything? On top of that Alaska Airlines didn't complete my ticket to the new flight. I wasn't sure I would get on this horrible flight, either. Oh, and it's ten o'clock at night....no food. Is this how Alaska Airlines treats its customers? I'll never fly with this airline again.

It was very comfortable. Personal entertainment screens would, of course, have been nice. And the flight in Seattle was delayed, but... things happen. All in all, I like Alaska Airlines very much.
